No it's a solid piece of aluminium, the gasket stops the vacuum leaking around the outside of the bed, fast and easy to put down, it works great.
It's satin black spray paint, it does look cool for a £6 a can! I was going to powder coat but its a little thicker than paint so decided to stay away. I'll be building another machine soon, might powder coat the frame on that one to save all the painting!
Hello really nice build.
Whad size steel are you using for the frame and the gantry?
